Document Summary
Dew is water that has condensed onto objects near the ground when their t s have fallen below the d. p. t of the surface air. In winter, however, this may form solid forms of dew. Frozen dew refers to dew (in the liquid state) which has formed and then freezes (to the solid state). water vapor to liquid to solid) * condensation occurs at a t above the freezing point, then the temperature continues to drop below the freezing point & the dew freezes. Frost or hoarfrost is a covering of ice produced by deposition because the d. p. t is below freezing. * water vapor changes directly to the solid state. Rain: water vapor condenses into liquid water droplets forming clouds. These droplets coalesce (join together) and become heavy enough to be pulled down by gravity as precipitation (a raindrop), if they do not evaporate before they hit the ground.
